Arrested key terror suspect Abdullah Sunata planned to attack the police’s anti-terror squad on July 1 to coincide with Police Anniversary Day, an official said Friday.
Abdullah’s group also planned to attack a European embassy in Jakarta, National Police spokesman Insp. Gen. Edward Aritonang said.
The attacks were intended as retaliation for the squad’s recent series of successful raids.
The anti-terror squad, Detachment 88, captured three people, including Sunata, and killed a fourth in raids in Central Java on Wednesday.
Sunata tops the police’s most-wanted list for alleged involvement in previous bombings and for planning to assassinate President Susilo Bambang Yudhoyono and foreign guests on Independence Day ceremony, Aug. 17.
Previously, police arrested another suspected terrorist, Mulyono, his wife and two children and confiscating explosives and weapons in a raid in Girimulya village in the same district.
Police have been hunting for Sunata on suspicion of running a militant training camp in Aceh and for recruiting terrorists.
Police have arrested 61 suspected militants and killed 14 in a series of raids since February, after authorities broke up a training camp run by al-Qaeda in Aceh, a previously unknown terrorist group.
In 2006, Sunata was sentenced to seven years in prison for weapons possession and for hiding Noordin M. Top, a Malaysian wanted in connection with five major bombings in Indonesia.
Noordin was killed by police in September 2009. Sunata was released in April 2009 for good behavior but rejoined to the terrorists.
